O. H. MOLOMOT MARKING DEVICE Filed July 24, 1958 3'l56789l0ll FIG. 4- z3INVENTOR. OSCAR Mwonor @iwf/l MMLM Irramvsys United States Patent3,020,067 MARKING DEVICE Oscar H. Molomot, Minneapolis, Minn., assignorto 'Iruckers Specialty Printing Co., Inc., Minneapolis, Minn., acorporation of Minnesota Filed July 24, 1958, Ser. No. 750,668 1 Claim.(Cl.281-29) The invention herein has relation to a novel and improveddevice useful for a variety of purposes but especially useful for thepurpose of placing line markings on charts, commonly known as truckdrivers daily logs, which the Bureau of Motor Carriers of the U.S.Interstate Commerce Commission requires to be kept by each truck drivercrossing a State line. This for the reason that the law requires adriver to have a stipulated number of hours of rest between drivingassignments.

In practical operationthe charts, or drivers daily logs are ofduplicateconstruction andbound together in tabletV form. Each is constituted as aat sheet of paper, or the like, having indicia thereon. Moreexplicitly,V the pertinent matter on each sheet is arranged in fourvertically spaced, horizontal rows. The horizontal rows are, orv couldbe entitled Olf Duty; Sleeper Berth; Driving; On DutyNot Driving; andeach title is followed by calibrations denoting a.m. and pm. hours of asingle day. kI-Ieretofore, truck drivers have marked up the charts orlogs by placing thereon free hand horizontal lines to denote their timeoff duty, sleeping, driving and not driving, and vertical lines todenote their times of shift from category to category of the charts orlogs. Usually, the line markings are duplicated, as by placing a sheetof carbon paper between two superimposed daily charts or logs. Freehandentry of the lines has been unsatisfactory because of irregularity andcomplication of the tabulation off duty, sleeping, driving and notdriving times spent by` truckdrivers, and vertical lines are drawn todenote the times of shifting from one category to another, asl from Thenew and improved marking device consists of a index board 1'4, ofrectangular contiguration as disclosed,

and a marker 15, also rectangular, slidably assembled with said indexboard. j

The index board 14 can be of 4any material suitable to its use.Desirably, `it willbe relatively thin, of uniform thickness and'haverigidity. When to be put to'use, said index board will be placed insuperimposed relation to anV tions on the charts, logs or sheetsdenoting the a.m. and p.m. hours when the index board and said markerare ofk the information.v Verification of line markings e'viv dentlywillbe diilicult', or even impossible, in instances when the lines are freehand, and thus carelessly drawn.

The device of the application renders the marking of status lines onvthe chartsV or logs easier for truck drivers and more readily andaccurately decipherable than has heretofore been the case.

In the accompanying drawing forming a part of this specification,

FIG. 1 is a perspective view of a tablet having therein superimposed,detachable charts, each commonly known as a Drivers Daily Log, showing amarking device made according to the invention as when applied to use inthe placing of line markings on an uppermost chart or log in or of thetablet;

FIG. 2 is a plan view of the disclosure of FIG. 1;

FIG. 3 is an enlarged sectional view, taken online 3-3 in FIG. l;

FIG. 4 is an enlarged bottom plan view of a marker of the markingdevice; and

FIG. 5 is a detail sectional view, taken on line 5-5 in FIG. 2.

Referring to the drawings and the numerals of reference thereon, 10denotes a tablet having a plurality of duplicate superimposed charts orlegs 11 therein. Each chart or log 11 is constituted as a at sheet ofpaper, or the like, having indicia 12 thereon. Ihe indicia on all of thecharts, logs or sheets will be the same as the indicia on the uppermostsheet in FIG. 2 of the drawings, as well as identically situated. Thecharts, logs or sheets are detachable from the tablet along lines 13extending transversely thereof at a single side of and equally spacedfrom the indicia.

In FIG. 2 of the drawings, the indicia 12 is arranged in four verticallyspaced, horizontal rows. The uppersuperimposed upon an uppermost chart,log or sheet. Said indexboard and the marker can be situated insuperimposed relation to the charts, logs or sheets in anysuit* able andconvenient manner. As disclosed, a cover of or for the tablet includesupper and lower aps,rdenotedV 18 and 19, respectively, and the indexboard isintegral, as at 20, with an end of the lower flap 19 spaced fromthe. tear lines 13.

The marker 15 can be of any material suitable to its purpose. Desirably,it will be relatively thin and have rigidity. As disclosed, said markerconsists of transparent plastic or composition material, so-called. Abody 21 of the marker is relatively at, and each of opposite endportions of said marker is constituted as a centrally disposed,outwardly extending flange 22 and a pair of transversely spaced,outwardly extending flanges each denoted 23. The flanges 23 at each endof the body 21 are in a single plane substantially parallel with theplane of said body, the flange 22 at each end of the body is between andin spaced, parallel relation to the ilanges 23 at the same end of saidbody, and, together, the ilanges 23, 22, 23 at each end of the bodyprovide an outwardly opening guideway 24. The guideways 24, in the planeof the body 21 of the marker and in oppositely facing relation, are forsnugly receiving interiorly extending, marginal edge portions 25, 25 ofthe index board 14 which terk minate in the horizontal edges 17, 17thereof. The construction and arrangement will be such that when theindex board 14 and the marker 15 are assembled, the horizontal edges 17,17 of said index board will be adjacent to the opposite ends of the body21, as in FIG. 3 of the drawing, and said marker will be manuallyslidable longitudinally along the index board relative to thecalibrations on the charts, logs or sheets 11 in the tablet. Theopposite side edges 26, 26 of the marker will be in .perpendicularrelation to the index board transversely thereof when said marker andindex board are in assembled relation.

. Vertically spaced apertures through the marker 15 are Patented Feb. 6,1962 The next adjacent The next adjacent 'j indicated 27, 28, 29 and 30respectively The apertures 27 are longitudinally alined with the titleGif Duty and the calibrations corresponding thereto. The apertures 28are longitudinally alined with the title Sleeper Berth and itscalibrations. The apertures 29 are longitudinally alined with the titleDriving and its calibrations. And the apertures 30 are longitudinallyalined with the title On Duty Not Driving and its calibrations.

Transversely spaced, longitudinally extending ridges, each represented31, on the lower surface of the transparent marker are alined with thesets of vertical apertures 27, 28, 29, 30, respectively.

The manner of use of the marking device will be apparent. When orf dutytime is to be entered on a chart, log or sheet, a pencil, or otherwriting implement, will be inserted through an aperture 27 and caused todraw a 1ongitudinal line on the chart, log or sheet concurrently withmanual horizontal sliding movement of the marker. When sleeper berthtime is to be recorded, the writing implement will be placed in anaperture 28 and caused to draw a longitudinal line with Ymanualhorizontal sliding movement of the marker. Driving time and on duty notdriving time will be marked up while the writing implement is inapertures 29 and 30, respectively.

When at the expiraton of any of the condtons denoted by the titles, ashift of category is to be made, the marker will be slid longitudinallyof the index board to situate a side edge 26 of said marker at theappropriate position to serve as a straight edge or guide for directinga manually manipulated writing implement to travel transversely,upwardly or downwardly as the case may be, of the calibrations on achart, log or sheet.

The transversely spaced, longitudinally extending ridges 31 retain thebody 21 and flanges 22, 23 of the marker 15 in spaced relation to achart, log or sheet while a writing implement is operative thereon, thusto lessen liability of blotting when recording is done in ink. And, too,said ridges constitute or provide scribe lines by employment of whichthe apertures can be accurately located with respect to the calibrationson the charts, logs or sheets.
